The flight arrived on Tuesday morning from Newark, where the airline is piloting its free testing programme.
“Today is a really big day, it’s a fantastic milestone on the road to recovery as we come out of the pandemic,” said Aaron McMillan, United’s managing director – operations policy and support, who arrived at Heathrow on the service.
Passengers on the New York-London service are tested at Newark, with appointments made at least three hours before departure. They are still required to quarantine on arrival in the UK.
